Consider following simpliest script using Combobox:

package require BWidget
pack [ComboBox .cb -values {one two three}]

... or using Perl+Tcl::Tk
perl -MTcl::Tk=:perlTk -we "tkinit->ComboBox(-values=>[qw{one two three}])->pack;MainLoop"

I noticed few little misbehaviours on Windows system
When user clicks on arrow to performing dropping a listbox down,
first misbehaviour is titlebar of containing toplevel window redrawn
with a color of inactive window.
This misbehaviour in my opinion is irrelevant.
Second misbehaviour is that at some moment window could be dragged but
listbox does not becomes closed.

see screenshot at www.vkonovalov.ru/tcltk-misc/1st.JPG

to reproduce:
 - click on arrow of ComboBox widget, listbox should appear
 - click on a button of our script at Windows taskbar, toplevel should become active
 - after that toplevel could be dragged but listbox not closed, and it is clickable

sometimes latest step does not work (toplevel could NOT be dragged), in this case
misbehaviour could be reproduced by clicking on icon on taskbar once again (so app will
be minimized) and yet once again (and it will be restored) so toplevel could be dragged
afterwards

I saw this effect on Win2000 and WinXP.

This does not happens with Tcl/Tk 8.5, so visually behaviour is better.

perlTk does not have good combobox at all, so no good alternate to check on that side.
(I tried Tk::JComboBox, Tk::HistEntry, Tk::BrowseEntry, but those have their own
limitations and misbehaviours, and most of them look non-natively on Windows)
